>  What is the status of 2.04?

If we can get the people who know about 2.04-related unfixed bugs to
summarize, maybe we can just release it as-is and put off those fixes
for a quick 2.05.

If you're interested in helping, please start with cvs.

For djgpp, post them to djgpp-workers AT delorie DOT com

gcc-patches AT gcc DOT gnu DOT org

but you need to get the OK of the original patch author, and find out
why they haven't been contributed yet - there may be djgpp-specific
reasons to keep it out of the general sources.

That might mean it's hardcoded for the newer features.  Automated
testing for djgpp features is tricky at best.

You could try a native djgpp build, assuming you have LFN.
